摘要：

The use of clusters of polyatomic molecules with a relatively low ionisation energy (similar to 10 eV) is proposed for the efficient production of X-ray radiation. We have observed for the first time the generation of characteristic X-ray radiation due to L transitions in iodine atoms under the high-intensity femtosecond laser irradiation of molecular CF3I clusters, which were a small admixture to Ar carrier gas. The X-ray conversion efficiency amounts to similar to 10(-6) (for a yield of similar to 10(7) photons per pulse), which is an order of magnitude higher than the efficiency we obtained in the case of argon clusters under comparable conditions.
